Preparation of Super Absorbent Resins with Nitrocellulose Li Li, Xu Bin, Zhao
Baochang#, Yang Dong# Abstract Copolymers
of nitrocellulose(NC) and acrylic acid salt are synthesized as super absorbent resins(SAR)
from waste NC fiber and NC products. The influences of such factors as composition of
comonomers, initiator, crosslinking agent and neutralizer on the absorption capacity of
the resins are also discussed. The optimum absorption capacity of the obtained SARs is
952g/g, 73g/g and 3g/g in distilled water, 0.9% NaCl solution and 50% alcohol solution
respectively. The obtained SARs are not inflammable. 利用硝酸纤维素合成高吸水性树脂 李
